Abstract

Les éoliennes en mer classiques ne peuvent pas fournir d'énergie en cas de tempête ou d'absence de vent, car elles doivent être arrêtées en cas de tempête et aucune énergie ne peut être convertie si le vent est trop faible. En outre, il existe sur la côte et dans les eaux intérieures de nombreuses sources d'énergie potentielle inexploitées provenant des mouvements d'eau, qui n'ont pas encore été utilisées. Selon l'invention, un flotteur est équipé d'une roue dentée d'entraînement et est déplacé vers le haut le long d'un rail denté en raison des variations de niveau à l'intérieur de l'eau. L'énergie cinétique du mouvement ascendant est convertie en énergie électrique. L'invention peut être mise en œuvre aux différents endroits où de telles variations de niveau apparaissent et où un espace d'installation suffisant est présent pour un flotteur selon l'invention.
